French custom vehicle builder Lazareth debuted their newest creation called LM 847 at the 2016 Geneva Motor Show. The company started with a Maserati 4.7 L V8 normally used in a Quattroporte or Alfa Romeo 8C and built a leaning quad around it. The engine produces 470 horsepower and 457 lb-ft of torque and sends it through a one-speed hydraulic coupler to twin rear tires. The bike has a 1,850 mm (72.8 in) wheelbase and weighs 400 kg (881.8 lbs).
